POSED IMPRESSIONS This invention relates to printing presses and hasspecific reference to a press for color printing of graphic logs on longnarrow strips of material to be printed.

It is a common practice now in the drilling of oil or other wells tokeep a Well Log, which gives a graphic record in colored transcriptionof the different strata of earth penetrated in the drilling operation.The geological departments of the oil industries consistently use suchlogs. Heretofore, the procedure in making the logs is to use colored inkor pencil applied by hand to a base form printed on a long narrow stripof paper marked ofi in intervals of drilling depth. One size of formused comprises a strip of paper approximately five feet long and threeinches wide lined transversely over the length of the sheet at one inchintervals each representing 100 feet of well depth. A inch wide stripruns along the left side of the log, and this strip is subdivided intoinch wide spaces, each representing ten feet of well depth.

Several copies of the well log are usually required, each an exactduplicate of the other. However, rarely are more than 10-20 copies ofthe well log required. It will be seen, therefore, that accuratelypreparing these copies by hand would be a painstaking, tedious and timeconsuming process, while a conventional press andoperating it withsuflicient accuracy for exact color registration would be prohibitive.Moreover, a conventional press, such for example as a proof press whichis satisfactory for black printing, is inherently not sufiicientlyaccurate in operation to give overprinting registration necessary forcolor printing of the type discussed. Attempts to use color photographyand colored typewriting processes have proved unsuccessful. In short,the hand coloring of well logs has heretofore been better and cheaper.

Therefore, it is a primary object of this invention to provide aprinting press for a multicolor process on an elongated strip ofmaterial to be printed and capable of correct multicolor registration.

Another object of this invention is to provide a press for printing anelongated strip of material having a paper supporting matte associatedwith accurate collimating means and clamping means for holding thematerial to be printed immovably in place throughout its length toinsure against travel of the material during successive overprintings.

Another object of this invention is to provide a printing press having apress roll which is geared to passover said material to be printed innon-slipping contact-so that successive colors may be printed on saidmaterial in correct color registration.

Another object of this invention is to provide a printing press forprinting an elongated strip of material having at least one type holdingchase in which the type is locked in position by lateral pressure sothat the type will not move from its correct position during successiveprintings and so that vacant spaces may be left in the printing surfacewhere desired.

Another object of this invention is to provide a printing press. havingat least one chase in which the type is easily set and held in trans-'verse-cut slots.

Another object of this invention is to provide a printing press havingtwo lift-out rollers which are readily removable to speed up themulticolor process and which whenremoved leave all the remaining rollersuncontiguous to facilitate cleaning.

Another object of this invention is to provide a printing press havingan inking roller unit with contiguous rolls therein of differentdiameter so that each roll makes contact with its neighbor roll along adifferent line on each revolution to more evenly distribute ink andreduce roll wear.

Still another object of this invention is to provide a printing pressfor applying a multicolor process to anelongated strip of material to beprinted which is easy'to set up for operationand in which correctionsmay be readily made.

With these and other objects in view, reference is made to theaccompanying drawings and detailed description thereof which is setforth for the purpose of explaining the invention in its preferredembodiment, but which is not meant to limit the scope of the inventionexcept as defined in the appended claims.

In its broadest concept this invention embodies a printing press forprinting a multicolr well log in correct color registration on anelongated strip of material to be printed. Means are provided forcorrectly registering each strip of material on a matte on the press andfurther means are provided for locking the material in place along itsentire length on the matte. Type which is. set in transverse cut slotsin a chase to be used in the press is easily set and allows the chaseand type to be locked in place by a' member exertin lateral'pressurealong the entire length of the chase. provided with mechanism whereby itcontacts the printing matte when moved in only one direction and wherebythe roll rotates. at a peripheral speed equal to the movement alongthematte to prevent relative movement of the'paper to the type. Aninking roller unit is provided with readily removable lift-out rolls forquick color changes and contiguous rolls of different diameter to insureeven distribution of ink'therein and means are included for alternatelylooking out the press roller unit and the inking roller unit as thematte is respectively positioned in a loading or a printing position.

Referring particularly to the drawingsFigures 1 and 2 show the printingpress. In of'this invention in broken up longitudinal sections. Anelongated frame ll acts as a support for the press. Standards or bearingposts l2, preferably of bronze, are spaced at intervals along one side,1

of the frame to carry a round rail l3 which is journalled for rotationon said standards. A gear rack I4 is carried on a rail I which is on theother side of the frame and parallel to the round rail. Together theround rail and the geared rail form a track I6. A pressroller unit H. ismounted for movement along the track l6 and is parked at one end of thepress on said trackwhenthat unit is not in operation. 7

An inking roller unit generally designated as A press roller unit is 23is normally parked at the other end of the track from the press rollerunit. This unit comprises a group of rolls and gears to explained indetail in relation to Figure 8 later on. A lockout 24 is fixed on theround rail to hold the inking roller unit in its parking position whenit is not being used. Another lock-out Z5 is fixed on the round rail inopposite phase to lock out for the inking roller unitso that itmay bemoved over the central portion of the frame when the lock-out 24 is inposition to hold the inking roller unit back. Note that the lockouts donot obstruct the entirecircumference of the round rail, for when onelockout is turned downward, it leaves the rail free at that end of thetrack for the roller unit at that end to move along the frame.

Along the longitudinal center of the frame I! and between the rails ofthe track is a printing press bed. 26 for mounting at least one typecarryin chase 2? as shown in Figure 5. A matte frame 28 having a matte29 mounted therein is rigidly secured to and extends radially from theround rail to move with said rail as it is rotated. Ordinarily, theround rail is rotated in a 180 are so that the matte moves from ahorizontal loading position at the side of said frame I l to ahorizontal printing position over the bed 26. One or more arms 39 extendfrom the side of the frame H to support the matte when it is in theloading position.

The control mechanism A handle operated mechanism 3! is positioned atthe end of the round rail where the press roller unit is parked toactuate the round rail. This mechanism as shown in Figure 3 comprises ahousing 32 from which extends a crank shaft 33 on which is fixed a crankarm; 34 with a handle 35. A crank arm36 is fixed. to theinner end ofsaid shaft 33. the crank arm 36 through a gear crank 38. The gear 31engages a gear 39 which is fixed to the round rail I3. When the handle35 is in the position shown by the dotted lines, the matte is in theprinting position over the bed of the printing press. Also, the lookout24 holds the inking roller unit in its parking space. When the handle 35is in the position shown by the dotted lines, the matte is in theloading position on the extending plate. 30. In this position thelook-out 25 will hold the press roller unit in its parking space and theinking roller unit may be moved forward over the bed 26. It is to benoted that the gear crank 38 is positioned on the gear 37 by a pivotstud 38' in such location that when the matte is moved from one extremeposition to the other, it moves through its intermediate positionquickly but slows down to ease into the extreme positions. gradually.This provision prevents wear and tear onthe matte and provides theconventional slow approach to the type.

The matte and printing material clamp Finger clips 45 arearranged alongsaidshafts at.

intervals to clamp a material to be printed in A gear wheel 31 isconnected toplace throughout the length of the matte on both sidesthereof. The matte 29 includes a sheet metal base 46 with a rubbercovering 4'! for better receiving type impressions. Collimation pins orpegs 48 protrude from the rubber covering along one side of the matte atspaced intervals. The material to be printed is provided with holesalong one side thereof to register with the collimation pins on thematte. Thus, all sheets of material to be printed placed on the mattewill always be in the exact same position. With every sheet of thematerial to be printed placed on the matte in proper registration on thecollimation pins and the finger clips lowered into contact with thematerial to be printed, every sheet will always be registered in theexact same manner on the matte and held throughout its length againstmovement out of such registration.

A toggle coupling 49 is located on the matte at the end thereof towardthe inking roller unit and connects one rotary shaft of the matte withthe other so that when one is turned to clamp down on the material to beprinted the other will do so simultaneously. The coupling includes acrank arm 59 fixed to each shaft and a separate connecting bar 51joining each crank arm to the opposite extremities of a centrallypositioned plate 52 which is pivoted at its center 53 to the end plate43.

On the end of the matte toward the extension plate 30, there is an endplate 54 journalling the ends of the shafts 44 as shown in Figure 10.The end plate 54 has an upward extension 55 through which passes a pivotbolt 56. A head 51 covers one end of said bolt and a cotter pin 58 inthe other end holds the bolt against longitudinal movement. A latch 59is carried by the bolt 56 in a slot 69 of the extension 55. A spring59', shown in Figure 12, forces the bottom of the latch out from theslot 60. The latch is serrated on its upper edge for finger control ifdesired. A latch handle BI is fixed to the end of the inner shaft 44 bya positioning screw 62 so that the shaft will turn when the handle ismoved. The latch handle is slotted to receive an angular latch key 63which is pivoted within the slot at 64 and has a projection 65 beyondthe slot for hand operation. A spring 63 pushes the key to extend it outof the slot toward the latch. As shown in Figure 12,..the key 63 fitsinto a recess 66 within the edge of the latch 59 to lock the latchhandle in place. When the latch handle is down as in the locked positionthe finger clips on the shaft 44 are clamped down against the matteand amaterial to be printed placed thereon. The latch handle turns the innershaft to which it is attached and that shaft in turn actuates the togglecoupling to turn the other shaft to the clamped position.

Though the material to be printed clamping mechanism just described canbe operated by hand, it can also be operated automatically. The plateextension 30 of theframe H is bolted to the frame by a bolt 81. Anangular control member 68 is pivoted to the extension 39 at 69 forlimited movement thereon. The control member 68 has an angular surfaceon its extreme end at 10. A spring H gives resiliency to the controlmember when the member is contacted.

When the matte is returned to the loading position from theprinting'position, it swings in an are so that the latch 59 contacts theend of the control member 68 at the end 10. A forward sloping edge 12 ofthe latch 59 slides along the end and forces the latch backinto therecess against the spring 59'. The latch is thus moved away from the key63 so that the latch handle is free. Since the key 63 protrudes fromthe'inner side of the latch handle, the key is caught on the end 10 asthe matte swings further down into the loading position. Thus the latchhandle is suspended to keep the shafts 44 turned to, a position whichunclamps the clamping fingers thereon. To reclamp the clampingmechanism, the key 63 is actuated by hand operation of the projection 65to remove the key from the surface end 10 of the control member. Thelatch handle then falls to the position shown in solid lines in Figure10, the clamping position.

The press roller unit 5 The press roller unit shown in Figures 3 and 4is contained in a housing 72. A press roll 13 is suspended within thehousing on a pair of pivoted side plates 14 on either side thereof. Anaxle 15 runs through the roll 13 and is journalled in the side plates.The housing has a front gear wheel '16 and a rear gear wheel 11 on oneside and normal Wheels 15 and T! on the other side. The front wheels arejoined by an axle l8 and the rear wheels by an axle 19. The rear gearwheel 1'! drives a gear 89 on a stud shaft 8|. Another gear 82 on thestud shaft drives a gear 83 on the press roll axle to turn the pressroll. These gears are arranged in a ratio such that. the press roll willroll in non-slipping contact over the back of the matte as the pressroller unit is pushed forward.

The side plate 74 on the gear side of the unit is anchored on to the endof the stud shaft 8| The stud shaft is supported on its inner end by apositioning plate 84 which is bolted to an upper bar 85 and a lower bar86. On the normal wheel side of the unit the side plate 14 is anchoredby a through bolt 8'! and a spacer ring 83 to the side of the housing. Alifting bar 89 is attached to the forward end of each side plate 14 toraise same. The upper end of each bar 89 is connected to a crank arm 90which is fastened by screws 9| to a bar 92. An operating lever 93 with aknob 94 is attached tothe central portion of the bar 92 and extendsthrough a slot 95 in the top of the housing.

The inking roller unit The inking roller unit 23, as shown in Figure 8,has a carriage 99. The gears for driving and operating this unit are allarranged on one side thereof. A drive gear 91 is carried by a transverseaxle 98 at the rear of the carriage. A wheel 99 on axle 98 as shown inFigure 7 supports the inking roller unit on the rail [3. A gear I99 isfixed to the axle 98 transmitting power from gear 9'! to operate therolls of the unit as the inking roller unit is pushed forward on thetrack. The gear Illll meshes with a supply roll gear "H, which in turnmeshes with a transfer roll gear I02. Gear I02 engages a largedistribution roll gear I03 which drives a forward inking roll gear H9and a rear inking roll gear III at the bottom of the carriage. Aneccentrically mounted gear H2 at the front of the inking roller unit isnormally disengaged from the gear rail, but is engaged with the gearrail when the unit is pulled back to its starting place to raise theinking rolls from the type during the initial distribution of ink on therolls and during cleaning. The axle I I3 which carries the idler H2carries an eccentric idler wheel and handle (not shown) on its otherend.

ampere Figure 2-1 shows how thegears are supported by a longitudinalplate H4= held in spaced relation to the side of the carriage 98byspacers- A supply roll H9 carries the ink initially and transfers itto a transfer roll I25 which places. The latter. roll ink on thedistribution roll IZ I distributes ink tofront and rear inking rolls I22and I23 respectively for inking the type. The supply roll andthedistribution roll are also lift-out rolls designed-for easy removalforquick operation of the multicolor process. In Figure 9 one of thelift-out rolls has a fixed axle I24 borne by bearings I25 in thecarriages 96 and the plate H4. A removable axle I26 is connected at oneend for rotation with the fixed axle by a multi-jam coupling I21. Theother end of the axle I26 is held in a detent I23 within the carriage. Asteel ball I29 is forced outward from a tapered hole I30 by a spring I3Iwhichv isheld by a screw 132. The ball is greater in diameter than theend of the hole so that it cannot come out. The end of the axle I26 isprovided with a curved surface which engages a" portion of the ball tohold the axle firmly but also so that it can rotate. By lifting on theaxle I25 at the end toward the detent it is easily snapped out of theinking roller unit. When both lift-out rolls are removed, none of therolls remaining in the unit are touching one another. This enables easycleaning, saves ink, and in addition, prevents flats in the rolls whenthe unit is out of use. Note also that all gears remain engaged at alltimes even if the lift-out rolls are removed in order to expeditecleaning and prevent damage to gears in handling. All rolishave the samediameter as the gears which drive them so that they will contact eachother without slipping against one another.

The type chases The type and method of setting same for the printingpress of this invention is shown in Figures 13-17. The chase block 27 ofthe color printing chase is preferably made of hard aluminum alloy intowhich are cut transverse slots I33. Steel spacers I3 are set into theslots. Clips I35 are punched into the steel spacers to secure them in avertical position within the slot. A type slug I36 is used on the colorchase. For printing spaces for descriptions on the log, numerals andtransverse lines marking the 100 foot sections are printed by-a typeslug I3? which is employed in a description chase I38. Linotype slugsbearing the descriptive word of the well sample taken are insertedbetween the adjacent slugs I3! with furniture spacers inserted to fillin the blank spaces andhold the descriptive word slugs in firm printingposition. Since no over-printings of the description chase are required,accurate registry of thev words is not necessary. When printing incolor, a furniture spacer occupies the space of the description chase.

Fig. 1'7 shows how the type I35 is adapted to give greater variation tothe log by having symbols cut in its printing surface, and how theprinting surface of the type may be partly cut away to show degrees ofsymbolizing. The type slugs are made to have some clearance between thespacers so that they. may be set more quickly. A black log chase forprinting the division lines between- :back to its parking. space.

The chase lock A unique chase lock has been devised to lock these-chasesin the bed of the pressframe. In Figures 6 and '7, the bed has themovable side I40 and a stationary side I40. Soft material- I4I lines theinside top andbottom of the movable side. Plates I42 are positioned'atintervalsalong the outside of the movable side of the bed; A connectingarm I43 joins the plate I42 with a crank arm I44which is fixed to apivot shaft I45. The shaft I45- extends through the side of the frame IIand has another crank arm I46 on its lower end; A- connecting rod I47connects all the crank arms I45 along the side of the frame II toactuate same in unison as a handle I48, as

shown in Figure l, is moved to-apply the chase lock. Thus all chases andany furniture spacers which may be used are locked in one operation.

Even pressure is-applied throughout the length of" the chases, and theindividual type slugs are locked in place between the movable andstationary side of the bed. In this manner the type is not dislocated bylongitudinal compression of the type from one endof the elongated chaseto.

In accordance with the invention, the chasesare compiled and thentheappropriate chases areplaced into the bed of the press-and locked. Theappropriate color'of ink isapplied to the supply roll of the inkingroller unit. The inking unit is moved backand. forth out of. contactwith the type and the ink isdistributed evenly on the inking rolls dueto the different diameter of the rolls.

The material to be printed or paper which has been appropriatelyperforated is placed on thematte in proper registration over thecollimation pins andithen the paper clamp looks it in place. The inking.roller unit is broughtinto contact with the type and rolled. back andforth over it. :once.. Theimatte is closed and the press roller swung.back to the loading. position,v the paper clamp is automatically openedon. both sides of' the paper and the log paper'can be removed. Theoperation is then repeated for other printings. It isto be noted that bycutting the paper to be used withthegrainrunning. the long way and byper.- forating only the amount of paper to be printed atone run,greater. accuracy in collimating' the paper is achieved.

From the foregoing-it is apparent that the press of. this inventionensures themost correct color regist-rationin' the printing. of amulticolor log on' an elongatedistrip of) material to b'e'printed. Notonly is the material to be printed carefully registered'and clamped'inplace throughout its length, but the type is held firmly. againstdislocation throughout its length. as well; In. addition, the press rollis incontact withthe matte while moving. in: only one. direction toavoidtravel of. thethe ten-foot. well depth. intervals, and also for. 75.matte oventhe type;

When the matte is.

' Furthermore, this printing press enables fast operation of amulticolor process. Not only may the type be set quickly, but spaces notneeded may be left vacant. Also, the paper clamp is partially automaticto speed up the loading of paper. The lift-out rolls are readilyinterchangeable and the ink rolls are easily cleaned.
